4.6 Installation of Battery
4.6.1 General Advice
Never place other equipment directly above the batteries
— gas from battery will corrode and
damage the inverter/charger.
Battery must to be installed in a well-ventilated area.
Battery must to be installed evenly with proper clearance between batteries.
Battery cables must have clear marks of Plus (+) and Minus (-).
Assure the connection cables to battery terminal are tightly screwed.
4.6.2 Connect the batteries
Several smaller batteries can be connected together to configure a battery bank of required size.
There are three ways to connect batteries: parallel, series or series-parallel.
To configure a larger battery bank, thick and heavy cables should be used to connect individual
batteries. The actual size of the cables depend on the maximum current which will flow through the
cables.
The size of battery cables should not be smaller than the size of inverter cables
— for example, if the cables between battery and Energier Pro is 16 mm
2
, the
interconnect cables among batteries is recommended 16 mm
2
, too.
The batteries which will be connected in parallel should be made by the same
manufacturer, and of same type and amp-hour rating.
4.6.2.1 Series Connection
When batteries are connected with the positive terminal of one battery to the negative terminal of
the next battery, they are connected in series. In a series configuration, the battery bank has the
same amp-hour rating as a single battery, but the overall voltage is equal to the sum of all individual
batteries.
